M.A. Ford Tuffcut End Mill

The M.A. Ford 156M0400N50A is a 2 flute ball nose end mill with a necked design and a 4.0 mm cutting diameter. It is manufactured by M.A. Ford for precision milling operations where contoured profiles and tight corner radii are required. The tool is sold new and ships directly from the manufacturer.

Machinists needing necked reach

This tool suits CNC operators who need extended reach in deep pockets or complex 3D contours without shank interference. The necked geometry provides clearance for the workpiece during side milling passes. Buyers who require a higher flute count for finishing passes or a larger diameter for heavy material removal should look at alternative tooling.

4.0 mm cutting diameter

The 4.0 mm diameter determines the minimum radius this cutter can produce and the stepover possible in profiling toolpaths. Select this specification only when the programmed feature size matches this exact dimension.

Questions about this item

How long is the necked section of the 156M0400N50A end mill?

The necked length is 50 mm, as indicated by the N50 designation in the part number.

Does the Tuffcut DM end mill generate significant heat during extended cutting sessions?

The solid carbide construction and two-flute design help dissipate heat, but sustained high-speed use will still raise tool temperature and may require coolant.

What shank size must my tool holder accommodate for this 4.0 mm ball nose cutter?

The shank diameter matches the 4.0 mm cutting diameter, so a 4 mm collet or holder is required.
